Thanks for posting your query.
You are most likely suffering from acute upper respiratory tract
infection with secondary bacterial infection.
Presence of cough
with sore throat
suggests the diagnosis.
You should consult with internal medicine specialist/ ENT surgeon and should go for thorough check up.
You should complete antibiotic course, mucolytic
and anti inflammatory, cough suppressants.
You should give rest to voice till complete recovery.
Perform gargle three times in a day.
Recovery may take 4-5 days more.
